I've seen a few episodes and some of the stuff is pretty amazing. Some of it have I seen before which doesn't make it as cool.

The samurai who was able to take a chunk out of a pellet shot at him. A man who can calculate advanced arithmetic and equations in his head before people can crunch them into a calculator. A man being able to power a like 3 amp blender through his body form the wall socket.

And so many more. I would link the videos but internet is being so slow right now it's impossible to do.
